HOW MUCH DOES A QUEEN WORTH?


This position is taken from a game I played last night at chess.com. Black just moved 23...Bg7. What is the best move for White?

The answer for the game between iiumchessmaster vs chess_ayotollah:

Option 1:
Saya fikir, to continue this game white should open the a-file and attack the black king. To do this white can play 24.Bxd5 Nxd5 25.c4 if black response with 25....Nxb6 and white will win the game by play 26.axb6+ if black play Kb8 27.Ra8+ Kxa8 28.Qa5+ Kb8 29.Qa7 checkmate.


Option 2:
If black play 26...Kxb6 27.Qa5 checkmate.


Option 3:
if black play 25....Nb4 26.d5 and white win bishop at g7.


That all possible moves which i can figure out..

Thanks for the reply.. but my move includes a queen sacrifice. And it doesn't involve a checkmate, just to obtain a superior position.. :)

By the way, Option 1 is not a checkmate. The King can safely run via c8-d7.

Option 2 is correct.

Option 3 will not win the Bishop. The Queen can guard it by Qc7.

And Option 4, the Knight can always return to f6.

ooop...sorry for option 1 thought the black still there, i forgot it already exchange..
that difficult to analyse without chessboard.

thank you

dear n@jd0rf,

this time i use chessboard to analyse that position and found the weakness in option 1 so the continue of
option 1:
29.Qa7+ black move king to Kc8 30.white play d5 attack the black queen. Black possible queen moves is whether Qe8 or sacrifice queen (there is no other square to save it. if 30...Qd7 31.Qa8 checkmate also). if black play 30...Qe8 31.Qa8+ Kd7 32.Qxb6 checkmate.


option 3:
yes i make mistake, use analyse board the black bishop is not gone yet the queen can protected it. i think 25...Nb4 is best move for black and give white several problem regarding g and h passed pawn and whether to exchange the bishop. if white exchange the bishop i think black get better position because it queen control a1-h8 diagonal.


can you give the rest of the move how you get the superior position

thank you.

You found a checkmate in option 1? Very good! (btw it's 32.Qxb7#).

However, 25...Nxb6 was not forced.

Mine was (actual game) taking advantage of Black's last move:

24.dxc5 dxc5, 25.Bxd5 Nxd5, 26.Bxg7 Nf4, 27.Bxh8 Rxd2, 28.Kxd2 with two rooks and a bishop for the queen. Hefty, eh?

Thanks again for your comments..
